초록
본 연구는 레진 표면을 연마한 후 레진 표면 강화재를 도포한 것이 표면 처리하지 않은 군에 비해 칫솔질 마모시 표면 특성 즉, 표면 조도, 표면 자유 에너지, 마모율 등의 변화가 있는지 알아 보기 위해 시행하여 다음과 같은 결과를 얻었다 (p=0.05). 1. 평균 조도는 Biscover < Forify < Polishing군 순이었다. 마모 전과 6개월에서는 모든 군에서 유의한 차이를 보였고, 1개월, 2개월, 3개월에서는 Polishing군과 Fortify군, Polishing군과 Biscover군에서 유의한 차이를 보였다. 2. 표면 자유 에너지는 마모 전은 Polishing군과 Biscover군, Fortify군과 Biscover군에서 유의한 차이를 보였고 (Biscover < Fortify < Polishing), 1개월에서는 Polishing군과 Fortify군에서 유의한 차이를 보였으며, 2개월에서는 각 군간 유의한 차이를 보이지 않았다. 3개월에서는 Fortify군과 Biscover군에서 유의차를 보였고, 6개월에서는 Polishing군과 Fortify군, Fortify군과 Biscover군에서 유의한 차이를 보였다 (Fortify < Polishing < Biscover). 3. 마모율은 1개월에서 모든 군에서 유의차를 보였으며, 2개월에서는 군 간 유의차가 없었고, 3개월과 4~6개월 평균마모율은 Polishing군과 Biscover군, Fortify군과 Biscover군에서 유의한 차이를 보였다. Fortify와 Biscover의 두께를 고려했을 때, Fortify는 2개월 내에, Biscover는 6개월 정도에 거의 소실되었다.
Abstract
This study evaluated the surface changes such as surface average roughness(RA), surface free energy(SFE) and wear depth among groups treated with surface penetrating sealant(Fortify, Biscover), non treated polishing group before and after tooth-brushing, analyzing the influence of the sealants in filling of surface microdefects formed during the finishing and polishing procedures of composite resin. Results were as follow(p=0.05): 1. Ra was increased Biscover, Fortify and Polishing group. Before abrasion and in 6 months, all groups were statistically significant. In 1 month, 2 months and 3 months no statistical difference was noticed between Fortify and Biscover. 2. SFE of Polishig and Biscover group, Fortify and Biscover group were statistically significant before abrasion. SFE of Polishing and Fortify group was statistically significant in 1 month. No statistical difference was noticed among groups in 2 months. SFE of Fortify and Biscover group was statistically significant in 3 months. Polishing and Fortify group, Fortify and Biscover group were statistically significant in 6 months. 3. Wear rate between Polishing and Fortify group was statistically significant in only 1 month. Wear rate between Polishing and Biscover group was statistically different in each month except for 2 month and so it was between Fortify and Biscover group. Considering film thickness of Fortify and Biscover, Fortify almost disappeared after 2 months and Biscover did after 6 months.
